Enhancement of the atomic absorbance of Cr, Zn, Cd, and Pb in metal furnace atomic absorption spectrometry using absorption tubes
文摘
The absorption tube achieved the enhancement of atomic absorbance in MFAAS. The tube-type absorption tube was effective for Zn and Cd. The intensities of Zn and Cd using the absorption tube were double of those measured without the tube. The method was successfully applied in the determination of Zn in tap water.
